CORE ABSTRACTION LAYER FOR TELECOMMUNICATION NETWORK APPLICATIONS

摘要

A new sub-system, the core abstraction layer (CAL), is introduced to the middleware layer of the multi-core processor based modem board. This new module provides an abstraction for the multi-core FSL P4080 processor and its DPAA. For the deployment of this modem board, the CAL will provide various services such as zero copy lock free buffer management scheme to LTE L2 application, and the support for the new backplane Ethernet driver (BED) interface for the RLC SDU transmission and reception to and from the controller board for multi-cell configuration.
